Airtac MTD Multi-position Locking Cylinder MTD6X20
The AirTAC Airtac MTD Multi-position Locking Cylinder MTD6X20 is a genuine MD multi-mount cylinder (single acting, pull type), 6 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 2.2 N of pull force at 0.5 MPa. A bumper cushions the impact.

About the Airtac MTD Multi-position Locking Cylinder MTD6X20
The MTD6X20 is an AirTAC multi-mount cylinder whose compact square body can be fixed from 6 directions - front, back, left, right, top and bottom - so units bolt side by side to save space on dense fixtures. This model is a single-acting, pull-type cylinder in a 6 mm bore with a 20 mm stroke: air pressure pulls the rod in and a spring returns it, suited to short, light release and positioning jobs. The 20 mm stroke sits at the top of the single-acting stroke range. The cushion is a bumper and the guide precision is high without added lubrication.
This is a genuine AirTAC part in the standard MD family (the no-rotating function belongs to the separate MK family). Operating pressure is 0.2-1.0 MPa (28-145 psi) on air filtered to 40 um, temperature range is -20 to 70 C (0 to 150 C only with the optional high-temperature seal material), and single-acting speed is 50-500 mm/s. This SKU carries no magnet. Overall dimensions and thrust figures for the pull side are per stroke and bore - confirm them from the datasheet and we will help you size the cylinder on request.

Specifications follow the official AirTAC MD/MK multi-mount data. The front cover and piston are short, so avoid an over-long stroke. An optional high-temperature seal material extends the range to 0 to 150 C. Overall dimensions vary per stroke and allowable side-load is published as curves — ask us and we confirm from the datasheet.
How to choose
Acting type is the first choice: MTD is single-acting pull, so air retracts the rod and the spring extends it; choose MSD if you need air to push, or the double-acting MD 6 mm bore for powered motion in both directions. Bore 6 is the smallest in the range for light loads. This 20 mm stroke is the maximum offered for single-acting variants, so there is no longer single-acting option in this bore. A trailing S on related models adds a magnet; this SKU has none. The M5x0.8 port is PT thread by default with G available. Remember the compact covers are not designed for over-long strokes, and confirm side-load limits from the datasheet through us.
Applications
Indexing pin release
Let the spring-extended rod drop into a locating hole on a rotary fixture, then switch air on to pull the pin clear so the table can index. The 6-direction body fixes wherever the tight station layout needs it.
Spring-up stopper gate
Mount the cylinder under a conveyor line so the spring-extended rod stops small parts at the station; applying air pulls the stopper down to release the flow, with side-by-side bodies keeping the footprint small.
Jig positioning pin
Use the spring-extended rod to seat a workpiece against a jig locator and air to retract the pin for loading and unloading. The compact 6 mm bore fits inside crowded fixture plates.
FAQ
Why is 20 mm the longest stroke I can order on this single-acting cylinder?
In the AirTAC MD/MK multi-mount range, single-acting variants (MSD push and MTD pull) are offered up to a 20 mm stroke, while double-acting variants go longer depending on bore. The compact covers are simply not designed for over-long strokes on single-acting units. If your application needs more travel, move to a double-acting MD model and confirm the stroke table and dimensions from the datasheet.
How is a multi-mount cylinder fixed, and what about side-load?
The square body is drilled so it can be fixed from 6 directions - front, back, left, right, top and bottom - and cylinders can be mounted side by side to save space. The allowable side-load and the overall dimensions for this bore and stroke are listed per model in the datasheet; confirm them with us before designing the fixture.
